Description

Type S non-reversing magnetic contactors are used to switch heating loads, capacitors, transformers, and electric motors where overload protection is provided separately. Type S contactors have ratings up to 810 amperes. This 3 pole NEMA Size 1 non-reversing contactor has a 27 ampere rating. Three phase NEMA Size 1 contactors have 7.5 HP at 200 and 230 VAC and 10 HP at 460 and 575 VAC ratings. This NEMA contactor has a 100 kA maximum SCCR rating per UL508A when protected by an appropriate circuit breaker or fuse. These contactors are available with replaceable coils in a wide variety of voltages. This contactor has a 110/120 VAC 50/60 Hz coil that is wired for separate control. This NEMA contactor is an open device without an enclosure. This contactor is 4.34 inches tall, 3.22 inches wide and 4.22 inches deep. A wide variety of accessories are available for Type S contactors. Type S NEMA contactors are UL listed and CSA certified.

Features

  • Designed strictly to the rugged NEMA construction standard, this Size 1 magnetic contactor ensures exact dimensional and performance compatibility when swapping out older or failing units in standard panels. It eliminates the physical alignment headaches common with compact IEC alternatives, allowing commercial electricians and industrial maintenance teams to complete drop-in retrofits without costly layout modifications.
  • Engineered for demanding industrial automation, this 3-pole, non-reversing contactor manages full-voltage starting for inductive motor loads up to 10 HP at 460/575V AC or 7.5 HP at 200/230V AC. The robust 27-Amp continuous current rating and an impressive short-circuit current rating (SCCR) up to 100 kA provide an ultra-reliable switching solution for heavy machinery, large heating loads, and high-capacity transformers.
  • Featuring a dedicated 110V AC @ 50 Hz / 120V AC @ 60 Hz dual-frequency coil, this model isolates high-power 600V system voltage from your control logic inputs. This configuration satisfies stringent facility safety codes and permits direct interfacing with standard pushbuttons, PLCs, and pilot devices without requiring complex control circuit step-down transformers.
  • Shipped as an open-type device with screw-clamp terminals, this contactor offers maximum installation flexibility for direct chassis or DIN-rail mounting inside custom-engineered NEMA-rated enclosures. This compact footprint layout optimizes panel real estate while ensuring the terminal connections remain highly accessible for rapid wiring, commissioning, and routine preventative torque checks.
  • Built for the grueling lifecycles of industrial environments, the Class 8502 Type S series features completely replaceable contacts and coils rather than requiring a full-unit swap. This serviceable architecture addresses a critical operational pain point by slashing future maintenance downtime and reducing long-term total cost of ownership (TCO) compared to disposable, non-serviceable components.
